The primary purpose of the slave server is to provide a backup to the primary master server should it go down for any reason. The major difference between the master server and the slave is where they get their data.
This tutorial describes how to set up database replication in MySQL using an SSL connection for encryption (to make it impossible for hackers to sniff out passwords and data transferred between the master and slave).

I run a master and slave Kerberos servers, which requires setting up kprop to run regularly on the master server in order to transfer any changes to the slave server.
This tutorial describes how to set up database replication in MySQL. MySQL replication allows you to have an exact copy of a database from a master server on another server (slave), and all updates to the database on the master server are immediately replicated to the database on the slave server so that both databases are in sync.
This example uses CentOS 6 so one of the issues you will need to be aware of is SELinux. The great aspect of a slave server is that you can update your primary DNS server and it automatically update the slave.
